Adjustment
To set the level of the subwoofer, use the OUTPUT
LEVEL control. Set it so that bass sounds are evenly bal-
anced with the treble sounds from the other speakers.
Because our ears are less sensitive to very low bass
sounds, there’s a temptation to set the level of the sub-
woofer too high. As a rule of thumb, set the subwoofer
level to what you think is the optimal level, and then back
it off slightly.

Caring for Your Speakers
Placement
• The speaker cabinets are made out of aluminum and
are therefore sensitive to extreme temperatures and
humidity, do not put them in locations subject to direct
sunlight or in humid places, such as near an air condi-
tioner, humidifier, bathroom, or kitchen.
• Do not put water or other liquids close to the speakers.
If liquid is spilled over the speakers, the drive units
may be damaged.
• As explained in this manual, mount the speakers on a
wall, on the supplied bases, otherwise, they may fall,
causing personal injury or damage to the speakers.
• Use commercially available speaker mounts and
brackets to mount the surround speakers on a wall.
• Speakers with bases should only be placed on sturdy,
flat surfaces that are free from vibration. Putting them
on uneven or unstable surfaces, where they may fall
and cause damage, will affect the sound quality.
Using Close to a TV or Computer
TVs and computer monitors are magnetically sensitive
devices and as such are likely to suffer discoloration or
picture distortion when conventional speakers are placed
nearby. To prevent this, the SKS-HT230 speakers feature
internal magnetic shielding. In some situations, however,
discoloration may still be an issue, in which case you
should turn off your TV or monitor, wait 15 to 30 minutes,
and then turn it back on again. This normally activates the
degaussing function, which neutralizes the magnetic
field, thereby removing any discoloration effects. If dis-
coloration problems persist, try moving the speakers
away from your TV or monitor. Note that discoloration
can also be caused by a magnet or demagnetizing tool
that’s too close to your TV or monitor.
The SKS-HT230 speakers contain strong magnets, so do
not put magnetic or iron objects such as screwdrivers
close to them. If you do, the object may be attracted to
the magnets, causing personal injury or damage to a
speaker cone.
Operating Precautions
The SKS-HT230 speakers can handle the specified input
power when used for normal music reproduction. If any
of the following signals are fed to them, even if the input
power is within the specified rating, excessive current
may flow in the speaker coils, causing burning or wire
breakage:
1.
Interstation noise from an untuned FM radio.
2.
Sound from fast-forwarding a cassette tape.
3.
High-pitched sounds generated by an oscillator, elec-
tronic musical instrument, and so on.
4.
Amplifier oscillation.
5.
Special test tones from audio test CDs and so on.
6.
Thumps and clicks caused by connecting or discon-
necting audio cables (Always turn off your amplifier
before connecting or disconnecting cables.)
7.
Microphone feedback.
